Trouble with digital PWM using an M-series Daq

Hello,

 

I am trying to control 8 independent digitally pulse width modulated Thermoelectric Peltier couples using the 6221 daq. I have tried using the digital PWM for M-series daq example that is available, but can only get the first line to output a signal.  When different lines are selected using the drop down menu, they create no output signal.  What am I doing wrong? 

 

Would this program (with some modifications) capable of running 8 different lines of signal?  All 8 signals will be run at the same frequency, with only the duty cycle needing to be independently changed, so I assume I will only need to use one counter? 

 

I have struggled with the example program for several hours, and cannot figure out why only the first line will output a signal. It says it was posted only a few days ago so I wonder if there is something wrong with it.

 

Any help will be GREATLY appreciated because I am at a standstill until I get this resolved 

 

Thank You

Hey,

 

I found an example which you could use to build up on it. It works on 8 lines.
